The only user of kobj_to_device_node() is in dynamic.c, so move it there. This avoids having to make it conditional once kobject is configurable. Tested-by:

Only Sparc and CONFIG_OF_DYNAMIC use the struct property._flags field, so make it conditional shrinking struct property a bit. Tested-by:

Only Sparc uses unique_id, so remove it for FDT builds and shrink struct property a bit making the unflattened DT less of a memory hog. Tested-by:

The ref counting is broken for OF_DYNAMIC when sysfs is disabled because the kobject initialization is skipped. Only the properties add/remove/update should be skipped for !SYSFS config. Tested-by:

With dependencies on a statically allocated full path name converted to use %pOF format specifier, we can store just the basename of node, and the unflattening of the FDT can be simplified. This commit will affect the remaining users of full_name. After analyzing these users, the remaining cases should only change some print messages. The main users of full_name are providing a name for struct resource. The resource names shouldn't be important other than providing /proc/iomem names. We no longer distinguish between pre and post 0x10 dtb formats as either a full path or basename will work. However, less than 0x10 formats have been broken since the conversion to use libfdt (and no one has cared). The conversion of the unflattening code to be non-recursive also broke pre 0x10 formats as the populate_node function would return 0 in that case. Signed-off-by: -

Commit 5620a0d1 ("firmware: delete in-kernel firmware") removed the entire firmware directory. Unfortunately it thereby also removed the support for built-in firmware. This restores the ability to build firmware directly into the kernel by pruning the original Makefile to the necessary minimum. The default for EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/. Fixes: 5620a0d1 ("firmware: delete in-kernel firmware") Signed-off-by:

The driver doesn't support events from address families other than IPv4 and IPv6, so ignore them. Otherwise, we risk queueing a work item before it's initialized. This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES is enabled, as the VRF driver will try to add an l3mdev rule for the IPMR family.

sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill returns err, in which case it shouldn't mark sk dumped by setting cb->args[3] as 1 in sctp_sock_dump(). Otherwise, it could cause some asocs to have no parent's sk dumped in 'ss --sctp'. So this patch is to not set cb->args[3] when inet_sctp_diag_fill() returns err in sctp_sock_dump().

Commit 86fdb344 ("sctp: ensure ep is not destroyed before doing the dump") tried to fix an use-after-free issue by checking !sctp_sk(sk)->ep with holding sock and sock lock. But Paolo noticed that endpoint could be destroyed in sctp_rcv without sock lock protection. It means the use-after-free issue still could be triggered when sctp_rcv put and destroy ep after sctp_sock_dump checks !ep, although it's pretty hard to reproduce. I could reproduce it by mdelay in sctp_rcv while msleep in sctp_close and sctp_sock_dump long time. This patch is to add another param cb_done to sctp_for_each_transport and dump ep->assocs with holding tsp after jumping out of transport's traversal in it to avoid this issue. It can also improve sctp diag dump to make it run faster, as no need to save sk into cb->args[5] and keep calling sctp_for_each_transport any more. This patch is also to use int * instead of int for the pos argument in sctp_for_each_transport, which could make postion increment only in sctp_for_each_transport and no need to keep changing cb->args[2] in sctp_sock_filter and sctp_sock_dump any more.
